BELL-RINGING DEVICE.

Application filed September'S, 1925. Serial No. 54,917.

My invention relates to mechanical bell ringing devices.

It is the object of my invention to provide a simple mechanical device for mechanically pulling a cable secured to a bell or to the clapper of a bell. It is further iny object to provide a mechanism Which will permit of a simple adjustment by `which the bell pulling stroke may be adjusted in accordance with the resonant qualities of the particular bcll with which the device is to be used.

Referring to the drawing in which l have n illustrated a rpreferred type of structure which is simple to install and which will fit Within the usual belfry; Figure 1 is a plan view of my preferred mechanism.

Figure 2 is a side elevation. Figure 3 is an end elevation. Generally indicated at 1 is apart of the supporting structure of the belfry which mounts the bell. Mounted in a frame com; posed of upright braces 2 secured in upper cap! members 3 and lower cap members 4 is the sheave pulley 5 Which is keyed to a shafta rotatably mounted in cross straps 6 from the upright members. Asimple mounting by which the frame may be secured to the supporting structure may be provided by eX- tending the upright braces through holes in the supporting structure and securing them with bolts. y Y

Also keyed to the shaft 5a is a pinion 7 which meshes with a driven gear wheel 8 keyed on a shaft 9 also secured in the cross straps 6. The shaft 9 has on its end a crank arm 10 through which movement is supplied to an oscillating compound lever. The com pound lever is composed of a' link 11 and a straight arm lever 12 which is adapted to be mounted in a plurality of positions by means of interspaced holes 13 which lit over a pin 14 mounted `on an upper cross strap. The end of the link is secured in a pivot in the end of the straight arm lever. To the other end of the lever is secured a coil spring 15 to which is secured the cable 16 which is adapted to toll the bell. A motor indicated at 17 connected with a belt may be suitably employed to rotate the sheave pulley 5;

The preferred arrangement Which I have arranged and which Was ascertained by ad- ]ustment to various pivot positions have extended shown that the proportions of the rocking lever 12 With relation to the link 11 should be as indicated in the figures Withvthe long arm of the lever'shorter than the length of the link and the short arin of the lever half as long as the long arm.

By rotating the sheaverpulley the crank arm moves the end of the lever 12 and the opposite end of the lever provides a movement to the cable of the bell Which is very similar to the effect which is given by manual operation. By mounting the lever 12 in the'different holes forming its fulcrum different effects can bel given dependent on Whether it is desired to toll the 4bell with. sharp staccato strokes or long resonant strokes.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is: y

1. A mechanical bell ringing device com-- prising in combination With a motor, a Wheel operable by the motor, a gear rotatable by the Operation of the Wheel, a crank rotatable with the gear, and a link actuated by the crank, a lever actuated by the link, resilient means connected with thel lever for tolling lthe bell and adjustable means of mounting the lever.

2. A mechanical bell ringing device comprising in combination With a motor and supporting members, a rotatable member opera tively connected with said moto-r, a crank operatively connected with said rotatable member, a link operatively connected to said crank, and a straight arm lever connected with said link at one end and to a bell cable at the other, said lever fulcrumed on said supporting member approximately one third the distance from said crank connection to the end thereof connected to said bell cable- 3. A mechanical bell ringing device comprising in combination With a motor, a rotatable member operatively connected with said motor, a crank operatively connected with said rotatable member, a link operatively connected to said crank, and a. straight arm lever fulcrumed and connected with said link, said link and lever being of proportionate lengths as follows, the lever fulci'umed so as to have a long arm of slightly less than the length of the link, and a short arm of approximately half the length of the ics long arm, the Connection of the lever and the operation of the Wheel, a crank rotatable with link being` from the short arm of the lever to the gear, a link actuated by the crank, a lever the link and said long` arm connected with a actuated by the link, means connected with 1e bell cable. Said lever for telling the bell, and adjust- 5 4. A mechanical bell ringing device' Colnable means for mounting the lever.
